随着电子信息技术的发展，无线传感器网络得到了日益广泛的应用，传统安全防护技术却无法直接应用于无线传感网中，传感器节点容易遭受到恶意攻击。该文提出了一种无线传感器网络的节点行为度量机制，对不同计算能力的节点采用不同的度量机制，具有实时度量和主动控制的特点。仿真实验表明，该方案充分考虑了无线传感器节点能耗问题，能够有效识别恶意节点，同时有更好的环境适应性，能够在部分节点遭到攻击时保障传感器网络顺畅运行。
The development of electronic information systems has led to many more wireless sensor networks. However, traditional security systems cannot be directly applied to wireless sensor networks, so the sensor nodes are vulnerable to malicious attacks. This paper presents a node behavior measurement mechanism for wireless sensor networks using different metric mechanisms for different computing nodes with real-time measurements and active control features. Simulations show that this method monitors the energy consumption of the wireless sensor nodes to identify malicious nodes while better adaptability to the environment to make the sensor network run smoothly when some nodes attack.
